For HubSpot teams who use Square for payments
Get paid on the HubSpot invoices you already send.
Your invoice, your numbering, your Square account. Collect on a card reader with the customer in front of you, on a branded checkout page, or let Square email it and chase the reminders — and the payment lands back on that invoice, itemized and marked paid.
- HubSpot plan
- Starter and above
- Custom objects
- None required
- Setup
- Two OAuth connections
- Processing rates
- Your own, unchanged
Connect once. Then it's four steps, every time.
Nothing to configure per invoice, no mapping screen to maintain, and no second system your reps have to remember to update.
-
01
Connect HubSpot and Square
Both by OAuth, from your own accounts. No API keys to copy and nothing pasted into a settings screen. Three minutes, once.
-
02
Your invoices show up on the deal
The invoices you already raise in HubSpot, with their balances, on the record your rep is already looking at. You keep your own numbering — we don't issue a second invoice.
-
03
Collect however the moment calls for
Charge a Square Terminal with the customer in front of you, send them a branded checkout page, or let Square email the invoice and chase the reminders. Same invoice, three ways out.
-
04
It writes itself back
A payment against that invoice, an order with the line items, the contact matched to its Square customer. The rep does nothing. Nobody opens Square to reconcile.
Every HubSpot record it touches
All standard objects. No custom objects to create, no schema to design, and nothing that needs an Enterprise plan — which is the usual reason integrations like this are out of reach.
| HubSpot record | What happens to it |
|---|---|
| Invoice | Read for its balance, then the payment is recorded against it and it stops reading as unpaid |
| Payment | One per payment taken, associated to the invoice, the contact and the deal |
| Order | Mirrors the Square order, so what actually sold is itemized on both sides |
| Line items | Copied per record — quantity, price, discount and tax, not just a total |
| Contact | Matched to a Square customer by email, or flagged for review when two people share one |
| Company | Kept as the billing entity where one is set on the deal |
| Product | Kept in step with your Square catalog |
| Deal | Payments associate back, so pipeline reporting reflects money actually in |
Refunds write back as their own record, so a refunded invoice stops reading as collected. Partial payments track down to the remaining balance rather than flipping straight to paid.
What you need
HubSpot Starter or above
For the invoices tool. Professional and Enterprise work too, but nothing here requires them.
A Square account
Your own, with your own rates. US sellers while we're in beta.
Three minutes
Connect both by OAuth. No API keys to copy, nothing pasted into a settings screen.
A Square Terminal, optionally
Only if you take payments in person. Everything else works without hardware.
Pricing
Unlimited seats on every plan. You keep your own Square account and Square's own processing rates — we don't add a percentage on top.

Straight answers
- Which HubSpot plan do I need?
- Starter or above for invoicing. Nothing here needs Enterprise.
- Do you touch card details?
- Never. Card entry happens in Square's own fields, and the reader talks to Square directly.
- What if two customers share an email?
- We stop and ask you rather than guessing. Matching the wrong person is how one customer ends up seeing another's invoices.
- Is it live?
- It's in private beta and we're onboarding a small number of businesses by hand. Get in touch and we'll be back to you before we open it up.
