E-commerce and integrations

If somebody at your company starts each morning copying PrestaShop orders into a3ERP, pasting SEUR tracking numbers into customer emails and lowering Amazon.es stock by hand, your shop sells well but is badly wired. We join the sales platform to your accounting package, payment gateways, carriers and marketplaces so each order travels from basket to invoice on its own, taxed correctly for the mainland, the Canary Islands or the rest of the EU, with Verifactu handled in the ERP. We work remotely with shops anywhere in Spain.

What data moves, and how often

Syncing everything every second sounds ideal and hardly ever is: it floods marketplace APIs and drags down the ERP in the office. Each kind of data gets its own rhythm.

Available stock

Every five to fifteen minutes, from warehouse to every channel. During campaigns such as Black Friday we shorten the gap and raise the safety buffer.

Prices and promotions

Several times a day, or whenever a promotion starts. Separate price lists for the website, each marketplace and trade customers, with a floor price per channel.

Listings, photos and attributes

In the small hours. Heavy volumes that, during office time, would slow the server running Sage or a3ERP.

Orders

As soon as payment clears, to the ERP and the warehouse. An order placed at 11 pm is ready to pick first thing, with nobody touching it.

Invoices and tracking

From the ERP and the carrier, back into the shop. Customers find the invoice and tracking link in their account, and the marketplace hears about dispatch in time.

Do not connect everything at once. Start with the flow that costs you most hours today, which is nearly always orders going into the ERP, let it run for two or three weeks and fix whatever turns up. Then move on to marketplace stock, payment reconciliation and labels. Switching on four links the same Monday means that when something breaks nobody knows where to look first, and staff lose faith in the tool before it has had a fair chance.

How we work

Everything is tested in a test company inside the ERP and in the sandbox environments of the gateway and carriers. A mistake in the live books is paid for in corrective invoices, and under Verifactu those corrections stay on record.

01

Following one order

We trace a real order from basket to booked payment and mark every point where someone currently copies, forwards or checks something by hand.

02

Rules agreed with your accountant

Tax by destination, invoice series, what happens to a part-paid order or a marketplace return. All written down before any configuration starts.

03

A full test cycle

Order, card and Bizum payment, invoice, label, tracking, return and credit note in the sandboxes. We only go live once every figure matches.

04

Launch and monitoring

We switch on the schedules and email alerts, then compare shop and accounting figures every week throughout the first month.

Common questions

Mainly PrestaShop, which is very widespread in Spain, plus WooCommerce, Shopify and Magento or Adobe Commerce. On each we first reach for the official modules from the platform, Redsys or the carriers when they cover what you need, and develop only the missing pieces. If your shop is custom-built, we connect it by API or through whatever files it can export.

Usually yes, though it takes more effort than cloud software. Some older on-premises versions of Sage or a3ERP expose no open API, so we use the vendor's connector, an intermediate service or scheduled file drops. Occasionally upgrading the ERP works out cheaper than working around its limits, and we will tell you so after inspecting the installation remotely.

The shop keeps selling on the last known stock figures and orders queue up until the connection returns; none are lost. Your nominated person and our team get an email alert. By Monday morning it is clear what happened, what was resent automatically and whether anything still needs a look, before any customer asks.

That depends on how many systems are involved, the state of the catalogue and whether official modules can do part of the job. A PrestaShop shop with Holded, Redsys and Packlink is far simpler than Magento with Sage 200, three warehouses and five marketplaces. We quote per project after the initial review, and later maintenance is billed at €75 per hour + VAT or as a monthly fee.

Always remotely, over encrypted connections and with restricted user accounts that you create and can switch off at any time. We do not visit your premises, sell hardware or handle parcels. If something physical needs doing beside the server, we send step-by-step instructions to whoever is on site.
