E-commerce Delivery Optimization for Dropshipping Sellers (2026)

Delivery optimisation for a dropshipping seller means making a delivery promise you can keep: a realistic handling time, delivery options buyers want, a tracking number that reaches the sales channel fast, and monitoring that catches late parcels early. In dropshipping the wholesaler ships, so the promise depends on data you do not control. This guide covers each part, with GAPLI facts as of 8 Oct 2026.

Key takeaways

• The delivery date a buyer sees is handling time plus carrier transit time; on Allegro the transit part is estimated from about a month of historical data.
• On Allegro, dispatch speed is worth up to 200 of the 400 sales-quality points, through the On-time dispatch and Fast dispatch metrics.
• A handling time should come from measured supplier dispatch times, not from the supplier's declaration.
• An order without a valid tracking number in the sales channel is invisible to the marketplace's delivery checks and generates "where is my order?" messages.
• Polish consumer rules require delivery without undue delay and no later than 30 days, unless agreed otherwise.
• At GAPLI the wholesaler ships directly to the customer, the tracking number goes back to the channel automatically, and GAPLI tracks the parcel until delivery.

What does delivery optimisation mean for a dropshipping seller?

It means controlling everything between the customer's payment and the parcel arriving, even though you never touch the goods. You set the handling time, choose which delivery options to offer, make sure tracking reaches the buyer and react when a parcel stalls. The wholesaler's real performance decides whether those promises hold.

Break the delivery promise into parts, because each one is optimised differently:

Part of the promise	What it covers	Who influences it in dropshipping
Handling time	From payment to handing the parcel to the carrier	Wholesaler's warehouse; you set the declared value
Transit time	From carrier scan to the delivery attempt or locker	Carrier and delivery option chosen by the buyer
Delivery options and price	Courier, parcel locker, pick-up point; shipping cost	Your shipping rate tables on each channel
Tracking	Number in the order so buyer and marketplace can follow the parcel	Wholesaler generates it; your system must pass it on
After delivery	Confirmation, invoice, returns	You or your platform

The parts multiply rather than add up. A fast carrier cannot rescue a handling time that slips by two days, and a well-kept handling time is wasted if the tracking number never reaches the order.

How do marketplaces judge your delivery performance?

Marketplaces compare what your offer promised with what actually happened, and they reward or penalise you for it. On Allegro the main signals are whether you dispatched within the declared handling time and how fast you dispatched. Offers with favourable delivery terms are shown higher in search results, according to Allegro.

Allegro's own rules, as published in its seller help centre:

Rule	What Allegro says
Estimated delivery time	The sum of dispatch time and transit time; transit is estimated by a model using roughly one month of historical data (Allegro Help)
Deadline for "immediately" or "within 24 hours" with a same-day dispatch time	Dispatch by 11:59:59 p.m. on the day the buyer ordered and paid (Allegro Help)
Parcels scanned after midnight	Parcels scanned by 8 a.m. the next day count as dispatched on the previous day (same source)
Points at stake	On-time dispatch up to 40 points and Fast dispatch up to 160 points, out of 400 sales-quality points in total (Allegro Help)
Market benchmark	Allegro states that more than 90% of orders on Allegro are dispatched on the next working day at the latest (Allegro Help)

One detail matters for dropshipping: the On-time dispatch metric also gives points when an order is delivered no later than the estimated delivery day shown at purchase. A slow dispatch can sometimes be offset by fast transit, but you should not plan around it.

How do you set a handling time you can actually keep?

Set it from what your supplier actually does, measured over recent orders, and add a margin for weekends and peaks. A declared "24 hours" that the warehouse meets only half the time costs you dispatch points and buyer trust. A slightly longer handling time that is always met usually performs better than a short one that is often missed.

A practical method:

1. Collect the time from payment to the first carrier scan for each supplier, over at least 30 recent orders.
2. Look at the slower orders, not just the average — the promise must hold for most parcels, not the typical one.
3. Set the declared handling time so that the large majority of orders dispatch within it.
4. Review it monthly and before seasonal peaks, when warehouses slow down.
5. Change handling time per product or supplier, not one value for the whole account.

Handling time in dropshipping depends on the wholesaler, which is why GAPLI syncs it to Allegro offers automatically, together with stock and prices. You do not maintain it per offer by hand; see the glossary entry on handling time and the GAPLI Allegro integration page.

How do you choose carriers and delivery options?

Offer the delivery options your buyers use most, at prices that match the market, and keep the set consistent across offers. In a dropshipping model the wholesaler's carrier contracts limit what you can offer, so the real task is mapping supplier capabilities to clean shipping rate tables on each channel and keeping those tables current.

Points to decide per channel:

• Option mix: courier to the door, parcel lockers and pick-up points. Offer only options the shipping warehouse can actually use.
• Shipping price: remember that on Allegro the commission is calculated on the price including the delivery paid by the buyer (Allegro Help), so shipping charges affect your fee.
• One table, many offers: manage delivery prices through shipping rate tables rather than editing offers one by one.
• Programme rules: some marketplace programmes, such as Allegro Smart!, set their own delivery terms; check them before you promise anything else.

How this works at GAPLI, from its integration pages:

Channel	Delivery set-up
Allegro	On connection GAPLI assigns the global shipping rate tables to the account; "Wysyłam z Allegro" (Allegro's shipping service) is supported; rate tables managed by Allegro under Smart! are read-only
Erli	Erli shipping rate tables are synchronised every hour; labels can also be bought through Erli shipping
WooCommerce	Delivery methods and pick-up points come from the GAPLI logistics network
Shopify	Once the parcel ships, the order is marked fulfilled with the tracking number

Why does tracking matter so much in dropshipping?

Because the tracking number is the only proof, for the buyer and the marketplace, that the parcel left on time. In dropshipping it is created at the wholesaler, so it has to travel through your system into the order. If it arrives late or not at all, buyers ask where their order is and delivery checks cannot credit you.

Allegro is explicit about this. For carriers in its second group, typically international ones, sellers must enter the tracking number themselves; numbers for the main domestic carriers are assigned automatically when you use Allegro's shipping service or the correct masked e-mail address. Orders sent with untracked options are excluded from the On-time dispatch and Fast dispatch metrics (Allegro Help).

What good tracking handling looks like:

• the number reaches the order in the sales channel as soon as the parcel is shipped;
• the buyer gets a message with the number from the channel itself, not a separate e-mail they might miss;
• parcels whose number shows no movement are flagged for a check with the supplier;
• the order is closed as delivered only when the carrier or marketplace confirms delivery.

At GAPLI the wholesaler provides the tracking number, it is added to the order in the sales channel automatically — Allegro, Erli, WooCommerce (as an order note) and Shopify (on the fulfilment, after which Shopify e-mails the buyer) — and GAPLI tracks the parcel until delivery. The order flow, step by step shows where tracking fits.

What delivery rules apply to online sales in Poland?

Unless the parties agreed otherwise, goods must be delivered without undue delay and no later than 30 days after the contract is concluded. If delivery is late, the buyer may set an additional deadline and, if it is missed, cancel the contract. These rules come from the Polish Civil Code and are summarised by the consumer authority UOKiK.

Three points matter for delivery planning:

Rule	What it means for you	Source
30-day maximum delivery period	Your offer's handling and delivery times must sit well inside it	UOKiK
Late delivery	The buyer can set an extra deadline and then cancel	UOKiK
14-day right of withdrawal	Counted from receipt of goods, so a late delivery also moves your return window	UOKiK

UOKiK has also warned consumers that long delivery times can signal dropshipping and that it matters who the seller actually is, because that decides who handles complaints and returns (UOKiK, 3 Dec 2020). Being clear about the seller and the expected delivery time is part of a good delivery promise. At GAPLI, GAPLI is the seller towards the customer and issues the invoice.

How do you stop delivery problems from turning into refunds and bad ratings?

Monitor every order against its promise and act before the buyer complains. Most delivery damage comes from a few predictable cases: orders with no tracking number, parcels that stop moving, deliveries slower than the estimate and products sold after they ran out. A short daily review of these cases prevents most refunds.

What to watch	Warning sign	Action
Orders without tracking	No number after the declared handling time	Ask the supplier; update the buyer
Stalled parcels	No carrier scan for two working days	Open a query with the carrier through the supplier
Dispatch against promise	Share of orders dispatched late rising	Lengthen handling time for that supplier or product
Stock-outs after purchase	Orders cancelled because goods are missing	Check stock sync for that supplier
Delivery messages	Rising "where is my order?" questions	Check whether tracking reaches the channel

The fourth row links delivery to stock accuracy: a parcel that can never be shipped is the worst delivery experience of all. The multichannel inventory sync guide covers how to prevent it.

When delivery fails anyway, handle it quickly and in the channel where the buyer bought. On Allegro, buyer messages, post-purchase disputes and ratings for accounts connected to GAPLI are handled in the GAPLI panel.

How does GAPLI handle delivery for its sellers?

GAPLI is a Polish full-dropshipping platform: the seller connects an Allegro, Erli or Aderlo account or a WooCommerce or Shopify store, and GAPLI supplies products from partner wholesalers, forwards orders, tracks parcels, issues customer invoices and settles the money. The wholesaler packs and ships the goods directly to the customer.

The delivery part of the order flow, as described on the How GAPLI works page:

1. GAPLI fetches the paid order from the sales channel. For Allegro and Erli accounts, the Fulfilment Pool pays for the order automatically; an order waits if the Pool has no funds.
2. GAPLI forwards the order to the wholesaler that holds the goods.
3. The wholesaler ships directly to the customer, and the tracking number is added to the order in the sales channel.
4. GAPLI tracks the parcel. Once the carrier or the marketplace confirms delivery, the order is marked "Fulfilled".
5. GAPLI issues the customer invoice in KSeF after delivery, and your commission becomes payable after the 14-day customer protection period.

As of 8 Oct 2026 the GAPLI catalogue had 980,891 products available for sale from 161 active wholesalers (GAPLI database). Live channels are Allegro, Erli, Aderlo, WooCommerce and Shopify; eMAG, Empik, TikTok Shop and eBay are in beta, and access is not yet open to everyone. Opening an account and the Start plan are free — see GAPLI pricing or create a free account.

Frequently asked questions

Does a shorter handling time increase sales?

Allegro says offers with favourable delivery terms are shown higher in search results and that a short estimated delivery time encourages buyers to purchase. But a short handling time only helps if it is met; missed deadlines cost On-time dispatch and Fast dispatch points. Choose the shortest time your supplier reliably achieves.

Who is responsible for the parcel in dropshipping, the seller or the wholesaler?

Towards the buyer, the seller is responsible, whoever packs the parcel. That is why the seller's offer must state realistic delivery terms and why returns and complaints go to the seller. In the GAPLI model, GAPLI is the seller towards the customer, while the wholesaler ships the goods.

What happens to an Allegro order shipped without a tracking number?

Allegro excludes orders sent with untracked delivery options from the On-time dispatch and Fast dispatch metrics, so they cannot earn those points. The buyer also cannot follow the parcel, which tends to produce messages and disputes. Use tracked options for marketplace orders.

Should delivery be free for the buyer?

It depends on the channel and your margin. On Allegro the commission is calculated on the price including the delivery paid by the buyer, so building delivery into the product price or charging it separately changes your fees and conversion. Compare both options on your actual numbers.
