Webshop orders from Shopify attach to the Teamleader contact that already exists, so a customer's quotes, invoices and purchases all stay on a single record instead of being split across two.
Teamleader already knows a lot of your customers. It holds the quote you sent, the invoice that followed and the conversation in between. Then the same person buys something on the webshop, and unless somebody checks, a second contact appears with the same name and none of the history. Nobody notices until a colleague quotes a discount the customer already has, or chases an invoice against the wrong record. The Shopify to Teamleader integration matches before it creates, so a webshop order lands on the customer you already have a relationship with.

An order is matched to the Teamleader contact that already exists, so a customer's purchase history sits with their quotes and invoices rather than on a record nobody knows about.
Webshop purchases appear against the contact, so whoever picks up the phone knows what the customer has actually ordered rather than only what was formally quoted.
Orders arrive with their lines and totals in place, so an invoice is raised from what was bought instead of from somebody reading the webshop and typing it out again.
Because payment status sits on the contact, nobody chases an invoice a customer settled last week, and nobody misses one because it was recorded against a duplicate.
A customer buys through Shopify and Alumio finds the existing Teamleader contact before creating anything, so the order joins the history already there rather than starting a second, emptier version of that same customer.
The order arrives in Teamleader with its lines and totals, so an invoice can be raised directly from it and the figures on the invoice match what the customer actually saw at the checkout rather than an approximation of it.
Where there genuinely is no existing contact, one is created from the checkout details, so the record starts complete and the next order from that person recognises them rather than quietly duplicating the whole thing again.
Alumio sits between sales channels and fulfillment systems as a governed integration backbone. Orders are routed, transformed, and validated, while status updates return to every channel.
Authenticate your systems using Alumio's pre-built connectors. Choose from 200+ connector packages in the marketplace, plus unlimited custom integrations.
Define how data fields map between systems in a visual interface. Adjust formats, enrich records, and apply business logic, no custom code required.
Configure flows to run in real time on events, on a schedule, or both. Reduce manual data entry and let Alumio handle movement and transformation between systems.
Once your first integration is live, adding your ERP, PIM, WMS, or CRM connects to the same hub. Existing flows keep running. No rebuilding from scratch.
Without an accounting package connected, the invoices Teamleader raises still have to be keyed into the books by somebody at the end of the month, which is the last manual step in this chain. Adding it uses the same customer matching, so an order, an invoice and a ledger entry all point at one customer rather than three spellings of a name.
Yes, and matching comes before creating, which is the part that decides whether this helps. Alumio looks for the existing Teamleader contact using the rules you set, usually email first, and only creates a new one when there is genuinely nobody to match. Orders then attach to that contact as they are placed.
No, and it is worth thinking about what the hand-built version does when one of the two changes something. A script written against today's fields breaks quietly when a field moves, and the person who wrote it has usually moved on. A configured connection is adjusted in a form by whoever notices. Custom logic stays available where a rule needs it.
By deciding what makes two records the same person, and deciding it before the first order arrives. Email is the usual answer and it is not always enough, because people buy with a personal address and get invoiced at a company one. Agreeing the rule, and what should happen when nothing matches confidently, is most of the work and it prevents the mess rather than cleaning it up later.
Alumio monitors every transfer as it happens and logs the customer and order it carried, so anything Teamleader refuses raises an alert immediately with the reason, and retries run where configured. What that catches is the failure people find hardest to unpick: a duplicate contact splitting one customer's history in two, so the invoice sits on one record and the order on the other, with nothing obviously missing to give it away.
