The client layer
Everyone you bill,
in one place.
Every client record builds itself as you invoice. Their details, every invoice you've sent, what they've paid, and how they tend to pay, all in one view. No separate CRM to keep up to date.

The record writes itself.
Add a client name on the first invoice and the record is created for you. From then on, every invoice, payment, and reminder attaches to it automatically. You never keep a separate contact list in sync.

Client intelligence
Know who pays on time.
Each client shows their real payment behavior: how fast they usually pay, what's outstanding right now, and whether anything is overdue. It's read from your own invoices, so you know who to follow up with and who to trust with terms.
Just enough, not a CRM
The client context you need, without the overhead.
A sales CRM is a system you have to feed. Wrenbase works the other way around: it keeps the client context an invoicing business actually needs, who you bill, what they owe, and how they pay, and it stays current on its own because it's built from the work you already do.
Projects · The organizing layer
Know what each engagement actually made.
In Wrenbase, every engagement is a project.
Group a client's invoices under a project and see what that engagement earned, all tied to the same client record.

Common questions
Quick answers.
- What is a client in Wrenbase?
- Everyone you bill. A client record holds their details, every invoice you've sent them, what they've paid, and how they tend to pay. It builds itself as you invoice, so there's no separate CRM to keep up to date.
- Do I have to set up clients before I can invoice?
- No. Add a name on the first invoice and the client record is created for you. From then on, every invoice, payment, and reminder attaches to that record automatically.
- What does 'who pays late' actually tell me?
- For each client you can see their payment history: how fast they usually pay, what's outstanding, and whether anything is overdue. It's drawn from your real invoices, not a guess, so you know who to follow up with and who to trust with terms.
- Can I import my existing client list?
- Yes. Drop in a CSV of clients from a spreadsheet, your CRM, or your phone contacts, map the columns once, and they're ready to invoice.
- Is this a full CRM?
- No. It's the client context an invoicing business actually needs, who you bill, what they owe, and how they pay, without the overhead of a sales CRM you'd have to maintain by hand.
- Does client data stay private to my business?
- Yes. Your clients and their history are isolated to your organization. A client record never crosses into another business's account.
