Estimates. Invoices. Payments. All In One Place.
Create professional estimates, turn approved estimates into invoices, collect payments, and keep everything organized inside your MONOLITHIC system.
Stop chasing paperwork.
Handwritten estimates, email, spreadsheets, invoices, text messages — and still wondering who has paid.
From estimate to paid, without starting over.
Once an estimate is approved, it can move into the invoicing process without starting over.
Professional, from the first quote to the final receipt.
Create professional estimates your customers can review and approve — then send invoices that look like they came from your business, because they did. Your invoice is another customer touchpoint, carrying the same brand identity as your website, email, and SMS.
Itemized and customizable for your business.
Branded with your business identity.
Give customers an easy way to pay.
Available payment methods can include the options below. Not every method is available on every account.
Automated reminders. Recurring billing.
Automated reminders can help keep invoices from being forgotten — they don't guarantee payment. For businesses with recurring services, recurring billing can reduce repetitive administrative work.
Invoices stay connected to the customer.
Your invoices and customer information can stay connected to the same CRM system you use to manage relationships and follow-ups.
See what's invoiced, paid, and outstanding.
Connected to analytics & reporting. Keeping financial activity connected to the rest of your business information can reduce duplicate data entry — MONOLITHIC doesn't replace an accountant or dedicated accounting software.
Automation reduces the repetitive work.
MONOLITHIC is AI-driven — automation can help with reminders, follow-ups, and customer communication. AI assists your business; it doesn't replace an accounting professional, and it doesn't guarantee payment.
Any business that sends estimates or invoices.
A more organized billing workflow can help — not just these industries.
Invoicing connects to everything else you use.
From a booked appointment to a paid invoice — your CRM, database, and analytics all stay connected, alongside outreach through database reactivation.
Estimate. Approve. Invoice. Get paid.
