What IT services & MSPs businesses open every day

The whole platform is included either way — these are simply the parts you'll live in.

  1. 01CustomersOne customer, one record — with every quote, invoice, booking and note attached, so nobody has to ask around for the history.
  2. 02ServicesDefine a service once with its rate and tax, then put it on any quote, invoice or booking page without re-typing the price.
  3. 03InvoicingSend a compliant invoice in your customer's language in under a minute — and keep every one of them in the same place as the customer, the product and the payment.
  4. 04StaffYour team, their roles, their departments and their salary history — in the same system as the work they do.

Retainers and projects, same invoice run

Define what you sell as services with their own rates and tax treatment, then bill monthly support and one-off project work from the same place. Quotes convert into invoices without re-keying, so the scope a client signed off is the scope you bill against.

What did we put on that site?

Hardware you've supplied or manage lives in the asset register against the client's location, with purchase value, current value and attached documentation. When a machine fails in year four, its history is a lookup rather than an archaeology exercise through old emails.

Built by people who read the API docs

One documented OpenAPI 3.1 contract sits behind everything, tenant isolation is enforced by PostgreSQL row-level security rather than application code, and every change is logged. If you evaluate tools by asking how they're built, that's the honest answer.

And everything else, included

There's no industry edition and no module you have to buy separately. Every plan includes every part of ERPFlow — what changes between plans is volume and team size, not which parts you can open.

IT services & MSPs — common questions

Does ERPFlow include a ticketing system?
No. There's no helpdesk, no SLA timers and no RMM. ERPFlow covers the commercial side — clients, services, quotes, invoices and the kit you're responsible for. Most MSPs pair it with the helpdesk they already run rather than replacing it.
Can I set up recurring monthly invoices?
Not automatically — there's no recurring invoice scheduler yet. You raise the monthly invoice, and duplicating the previous one takes a click. If you bill fifty retainers on the first of the month, that's real friction worth weighing.
Is there an API?
Yes. The product is API-first: a documented OpenAPI 3.1 contract that the web app itself runs on, so anything the interface does is available programmatically. An MCP endpoint, letting tools like Claude and ChatGPT work with your data directly, is on the roadmap.
