HubSpot + Global Shop Solutions integration

Global Shop Solutions sells one ERP for manufacturers, with estimating and quoting, scheduling, shop floor data, shipping and accounting in the same system, on premises or in a cloud Global Shop hosts on AWS. A won quote becomes a sales order in that system, and the prospect becomes a customer at the same moment. A CRM module keeps opportunities, contacts, campaigns and invoice history beside it.

Marketing and a growing sales team often standardize on HubSpot anyway, for forms, sequences, web tracking and a forecast they can share. Once they do, the truth about each account stays behind in Global Shop, and sellers lose sight of open quotes, job status, shipments and overdue invoices unless they ask the office. The office answers by phone and email, usually after the conversation that needed the answer has already happened.

Global Shop treats the connection as real work. Its integrations page lists HubSpot with a cost rating of four out of five and an effort rating of five out of five, and its own team describes building a one-off integration for every customer. That is a fair warning. Most of the effort goes on agreeing what moves where and who writes each side, and the design below is how we spend it.

Five records carry the relationship. Customers become HubSpot companies and their contacts become contacts. Quotes become deals, so the pipeline shows what estimating has out. Sales orders and invoices land as custom objects on the company, where a seller can see what is open and what is overdue.

Everything moves one way, into HubSpot. Global Shop converts a won quote into a sales order and a prospect into a customer by itself, and a second writer would only compete with that logic. Where a team wants HubSpot to originate quotes, that is a separate phase with its own import, written on the ERP side.

Keys come from the export: the customer, quote, order and invoice numbers Global Shop issues, each held in a custom HubSpot property. Names are for people to read. Contacts match on email, with the customer number as the tie breaker when two contacts share one address.

The pattern is an SFTP extract, transform and load. On the ERP side, a program written in GAB, Global Shop’s SDK, runs on a schedule and writes one file per object plus a manifest of row counts. Global Shop’s team or your own GAB developer writes it, and Global Shop says most customers keep an expert of their own to own an integration once it runs.

The files land on an SFTP drop. Our load service collects each one, hashes it so a repeated delivery is skipped, checks its columns against the agreed contract, and moves rows that fail validation to a quarantine with a reason. Clean rows go into HubSpot as batch upserts on the Global Shop numbers, followed by a separate association pass that links contacts, quotes, orders and invoices to their companies. The manifest doubles as the reconciliation: rows loaded against rows exported, reported on every run.

The first question is who writes the ERP side, because Global Shop publishes no public API reference and treats every integration as a one-off. Either its Continuous Improvement Team writes that side, or your own GAB developer does.

A custom integration puts the export behind a load service we build and run, so the keys, the delete signal and the reconciliation are ours to guarantee, and it is the route we recommend. Global Shop’s team can also build the whole link, which suits a business that wants one vendor for both sides. The marketplace app from Commercient is the third option, for a standard mapping, with its runtime and roadmap outside your control.

1. Scope. We meet your Global Shop administrator, and Global Shop’s team where needed, to settle the hosting, the records and who writes the export.
2. Architect. We write the file contract: columns, keys, the delete signal, the schedule and the manifest, plus the SFTP route.
3. Build. The load service is written against sample files, into a HubSpot sandbox with a portal allowlist from the first commit.
4. Validate. We reconcile every file against its manifest and compare open quotes and invoice totals with Global Shop reports.
5. Operate. We watch each run, keep a replay endpoint for any file, and re-check the contract whenever Global Shop is upgraded or the export changes.
