Connect only what you use. Nothing asks you to paste secrets. Client payments go to your Stripe account, typed e-sign is included, and the optional QuickBooks push plus Refresh keep books in QuickBooks.
From Settings → Billing, connect your own Stripe account with Stripe’s login. Invoice pay links then collect straight into your account — EstiLumina never holds client funds and is not the merchant of record for your job invoices.
Billing settings →Clients approve proposals and change orders on the portal with a typed name. It ships with every package; there is no separate e-sign product to buy for portal approvals.
Send for approval →Connect QuickBooks from Settings → Integrations and push the invoices you choose. Refresh compares those stamped documents. Your accountant’s books stay in QuickBooks — EstiLumina does not rewrite Collect amounts.
Integrations settings →Takeoff quantities export to an Excel file and import back on the same line ids, for the days you still edit offline. Everything else stays on the job record.
