Email Templates & Signature

Kantivo sends invoices, reminders, receipts, and estimates on your behalf. Rewrite every subject line and body so the messages sound like you, not like generic accounting software.

Where to Find Them

Kantivo ships with sensible defaults for the emails it sends customers, but the defaults are exactly that — defaults. To put your own voice on every outbound message, open Settings → Email Templates. Each template has its own subject/body/closing editor and saves independently.

The Four Templates

You can edit four template categories:

Invoice Delivery

The covering message that goes out with an invoice when you hit Send. Set the tone, mention the engagement, and lay out the payment terms. Kantivo attaches the invoice PDF automatically.

Payment Reminders

Aging reminders to clients with open balances. Each escalation stage — pre-due heads-up, first follow-up after the due date, and a firmer final notice — has its own template so the tone can ramp up naturally.

Payment Receipts

The confirmation Kantivo sends when you record a payment. Edit the thank-you, drop in any next-step instructions, and reference the leftover balance when the payment was partial.

Estimates

The cover note for estimates and proposals. Summarize the scope, call out the validity window, and end with a clear next-step ask (approve, sign, schedule a call).

Merge Variables

Merge variables are placeholders Kantivo substitutes at send-time. Drop them anywhere in the subject line or body and they'll be replaced with the right value for each recipient.

VariableSubstituted withSample output
{{customer_name}}Customer or business nameMaple Street Design Co.
{{invoice_number}}Invoice numberINV-2026-0087
{{amount}}Invoice total$3,200.00
{{due_date}}Date payment is dueApril 30, 2026
{{company_name}}Your company nameRiverstone Consulting LLC
{{balance_due}}Outstanding balance after any partial pays$1,100.00
{{payment_date}}Date the payment was receivedMarch 28, 2026
Tip: Variable names are case-sensitive and have to be spelled exactly. A typo means the placeholder ships in the email as literal text — and your customer sees the raw template syntax.

Signature Block

Every email Kantivo sends carries a signature block. Configure it once and it applies to all four template types:

Running multiple companies? Each one keeps its own signature.

Preview Mode

Click Preview on any template editor to see the rendered email with sample data plugged into the merge variables. It's the fastest sanity check before you let the template loose on real customers.

The preview renders both a desktop and a mobile layout — most of your clients will open invoices on their phone.

Resetting to Defaults

If you've edited a template too far in the wrong direction, hit Reset to Default on that template. Kantivo restores the original copy for that one template while leaving your other customizations alone.

Tip: Resetting affects future sends only. Anything Kantivo already mailed out under the prior template stays as it was.
