For agencies
Invoicing your clients.
Tracking your vendors.
Without three tools.
You bill clients on retainer and on project. You pay sub-contractors, freelancers, software vendors. Wrenbase gives you one ledger for every dollar in flight, in both directions.

Cash flow coordination
Know what's landed
before you approve what leaves.
Agencies don't fail from lack of work. They fail from timing. A retainer is late. A vendor expects payment Tuesday. Payroll is Friday. Wrenbase lines up incoming revenue and outgoing obligations so you can see what's landed before you commit what leaves.
Other tools track one side. Wrenbase tracks both, and shows you the timing between them.

Common questions
What every agency owner asks.
Question
How do I track money in and money out without juggling tools?
Client invoices, vendor bills, and payment records all live in Wrenbase. Outbound and inbound side by side. Search by client, by vendor, by month, by status. Export anytime. One source of truth for what's coming and what's going.

Question
How do I receive vendor bills without losing them in email?
Share your Invoice Me link with sub-contractors and vendors. They submit a structured bill with PO number, amount, and an attachment. The bill lands in your inbox with sanctions and fraud checks already done. No more chasing PDF attachments through Gmail.

Question
How do I handle different billing modes for different clients?
One client is on a $12K monthly retainer. Another is paying by project milestone. A third is hourly with a flat-fee retainer on top. Set the schedule and mode per client. Wrenbase handles each one on its own cadence.

Question
How do I keep my client invoices looking polished?
Your logo on every invoice on the free plan. Custom colors and theme on paid plans. The payment page your clients see carries your brand, not Wrenbase's. Enterprise clients with procurement teams get a billing experience that matches their expectations.

Question
How do I review and approve vendor bills before they're paid?
Every inbound bill lands in your Bills inbox with status New. Review the bill, approve it, then mark it paid when you settle (wire, ACH, check, card). The whole flow is tracked. Note: Wrenbase records the payment, you initiate it through your bank or Stripe.
