Typical case

Synchronising prices and stock levels across sales channels

Published 4 August 2026Updated 29 October 2026Qerify

Today prices and availability are set separately in the online shop, separately on Allegro and separately in the warehouse system. Changing one of those numbers means going into three dashboards, and a delay in any of them ends with an out-of-date listing.

Realistically you will recover from PLN 0 to PLN 0 a year

Here is the math: salary times the employer cost multiplier 1.2 divided by 173 hours a month gives the hourly rate. That rate times the hours in a year gives the cost of the process. From the recovery we take a band of 40% to 70%, because part of the time recovered on paper comes back as supervising the automation and handling exceptions. This is a deliberately conservative range, not a promise.

Where the hours go

Syncing prices and stock by hand across several marketplaces leads to mistakes and delays. With hundreds of listings, automatic integration becomes a condition for scaling safely.

The result of a delay is selling goods you no longer have, or keeping an outdated price after a promotion has ended. Both end in a conversation with the customer that does the company no favours.

What automation does

Price and stock level have a single source of truth, and a change there spreads to every connected sales channel without anyone lifting a finger. Product mapping between channels is set up once, during implementation, just as with order integration.

Promotion rules, such as a time-limited discount, can run automatically across all channels at once and end at exactly the set time, with no need to change the price back by hand.

What it costs and when it pays back

Implementation usually falls between 2,000 and 8,000 PLN, within the platform's API integration range, which goes up to 10,000 PLN. The price depends on the number of channels and whether each of them has a ready-made API for updating prices and stock.

Payback comes in the third to sixth month. Use the calculator to work out how many people and how many hours a week currently go into keeping an eye on prices and stock in several places at once.

Frequently asked questions

Usually 2,000 to 8,000 PLN as a one-off, within the platform's API integration range of 1,500 to 10,000 PLN. More sales channels and more elaborate promotion rules push the quote upwards.

Yes, as long as each variant has its own code in the warehouse system. Mapping variants is exactly the part of the implementation that needs the most attention at the start, and it is worth testing it thoroughly before going live with the full product range.

Usually within a few minutes of the change at the source. Some channels update data at intervals rather than in real time, so it is worth agreeing the exact timing in the quote for your set of tools.

A well-built synchronisation retries and reports an error if it still fails, instead of quietly leaving an outdated price in place. The other channels keep working regardless of one of them failing.
