Note the agent type, usage pattern, and any special pricing rules you\u2019ve promised. A spreadsheet works, but Donely\u2019s dashboard can export a CSV that shows usage per instance.<\/p>\n<p>Next, group clients by similar billing cycles , monthly, quarterly, or usage\u2011based. This grouping tells you where a single invoice makes sense and where you need separate line items.<\/p>\n<p>And ask yourself: does each client have its own isolated OpenClaw instance? If you\u2019re mixing data, the invoice will be a mess. Keep instances separate so the usage data stays clean.<\/p>\n<p>When you\u2019ve mapped the structure, you can design a charge\u2011back model that matches your contracts. For example, a flat\u2011fee per instance plus a tiered discount for high volume.<\/p>\n<p>Finally, review the map with your finance lead. Spot any overlap or missing cost centers before you build the invoice template.<\/p>\n<p>We recommend checking out <a href=\"https:\/\/donely.ai\/blog\/per-instance-billing-model-for-agencies\">Best Per\u2011Instance Billing Models for Agencies &#8211; Donely AI<\/a> for a deeper dive on how to align pricing tiers with client usage.<\/p>\n<h2 id=\"step-2-set-up-a-single-invoice-template-in-donely\">Step 2: Set Up a Single Invoice Template in Donely<\/h2>\n<p>Donely lets you create a reusable invoice template that pulls data from all client instances. Open the Billing tab, click \u201cNew Template,\u201d and choose the \u201cConsolidated\u201d layout.<\/p>\n<p>In the template editor, add placeholders for client name, total usage, and any discounts. The placeholders pull directly from the usage reports you exported earlier.<\/p>\n<p>Use a clear heading like \u201cConsolidated Billing Summary\u201d so the client knows the invoice covers multiple services. Below the heading, list each client\u2019s subtotal , you can hide this if you prefer a single total line.<\/p>\n<p>Donely also supports custom fields for tax IDs or purchase order numbers. Fill those in once, and the system will repeat them on every generated invoice.<\/p>\n<p>Before you save, run a test generate for a dummy client. The preview should show a single line total, with optional breakdowns underneath.<\/p>\n<div class=\"pro-tip\" style=\"background: linear-gradient(135deg, #fffbeb, #fef3c7);border-left: 4px solid #f59e0b;padding: 1em 1.5em;margin: 1.5em 0;border-radius: 0 8px 8px 0\"><strong>Pro Tip:<\/strong> Turn on \u201cAuto\u2011send PDF\u201d so the invoice lands in the client\u2019s inbox the moment the month closes.<\/div>\n<p>For a solid definition of what an invoice should contain, see <a href=\"https:\/\/en.wikipedia.org\/wiki\/Invoice\">Wikipedia\u2019s invoice article<\/a>. It outlines the legal elements you need to include.<\/p>\n<p><img decoding=\"async\" alt=\"A realistic dashboard view showing Donely\u2019s invoice template editor with placeholders and client usage charts. Alt: centralized billing invoice template setup in Donely\" src=\"https:\/\/rebelgrowth.s3.us-east-1.amazonaws.com\/blog-images\/guide-to-one-invoice-centralized-billing-for-multiple-clients-1.jpg\" \/><\/p>\n<h2 id=\"step-3-automate-client-allocation-and-payment-tracking\">Step 3: Automate Client Allocation and Payment Tracking<\/h2>\n<p>Now that the template exists, set up an automation rule that runs on the first of every month. Donely\u2019s workflow builder lets you pick \u201cGenerate Invoice\u201d and then \u201cSend to Client.\u201d<\/p>\n<p>Link the rule to the usage export you created in Step\u202f1. The system will sum each client\u2019s usage, apply any tiered discounts, and fill the template automatically.<\/p>\n<p>And add a payment\u2011status flag. When a client pays, the flag flips to \u201cPaid,\u201d and the next cycle starts fresh.<\/p>\n<p>Here\u2019s where a quick video can help. Watch the walkthrough below to see the rule in action.<\/p>\n<p><iframe allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen=\"\" frameborder=\"0\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/IG2LBzs3Lak\" width=\"560\"><\/iframe><\/p>\n<p>Automation also reduces human error. According to the <a href=\"https:\/\/www.irs.gov\/businesses\/small-businesses-self-employed\/recordkeeping\">IRS record\u2011keeping guidelines<\/a>, consistent, automated documentation helps you stay audit\u2011ready.<\/p>\n<h2 id=\"step-4-configure-rbac-and-audit-logs-for-compliance\">Step 4: Configure RBAC and Audit Logs for Compliance<\/h2>\n<p>Role\u2011based access control (RBAC) ensures only authorized people can see or edit billing data. In Donely, go to Settings \u2192 Security \u2192 RBAC and create roles like \u201cFinance Manager\u201d and \u201cAccount Executive.\u201d<\/p>\n<p>Assign each role the permissions it needs , view invoices, edit discounts, or approve payments. Keep the \u201cFinance Manager\u201d role limited to the billing module.<\/p>\n<p>Enable audit logs so every change to a client\u2019s bill is recorded with a timestamp and the user who made it. This log is essential if a client disputes a charge.<\/p>\n<p>And remember to export the logs quarterly. Store them in a secure bucket that meets your compliance standards.<\/p>\n<p>Donely\u2019s own guide on secure hosting walks through setting up isolated instances and audit trails. See <a href=\"https:\/\/donely.ai\/blog\/ai-employee-hosting\">AI Employee Hosting: Top Platform For Consultants &#8211; Donely<\/a> for more details on isolating client data.<\/p>\n<h2 id=\"step-5-deploy-integrations-and-scale-across-clients\">Step 5: Deploy Integrations and Scale Across Clients<\/h2>\n<p>With billing locked down, add the integrations you need , Stripe for payments, QuickBooks for accounting, and Slack for alerts. Donely\u2019s integration hub lets you connect each client\u2019s Stripe account individually.<\/p>\n<p>Set up a webhook that fires when a payment succeeds. The webhook updates the payment\u2011status flag you created in Step\u202f3.<\/p>\n<p>But before you roll out to all clients, run a pilot with two or three accounts. Check that the invoices arrive, the payments sync, and the audit logs capture every action.Once the pilot passes, duplicate the integration settings across the remaining client instances. Donely\u2019s bulk edit feature lets you apply the same webhook URL to dozens of accounts in minutes.<\/p>\n<div class=\"key-takeaway\" style=\"background: linear-gradient(135deg, #eff6ff, #dbeafe);border-left: 4px solid #2563eb;padding: 1em 1.5em;margin: 1.5em 0;border-radius: 0 8px 8px 0\"><strong>Key Takeaway:<\/strong> Centralized billing works best when each client lives in its own isolated instance, with separate integrations feeding a single invoice template.<\/div>\n<p><img decoding=\"async\" alt=\"A realistic scene of multiple client dashboards linked to a single Donely billing view, showing integration icons for Stripe, QuickBooks, and Slack.

If a client pays early, the system records the payment and marks the invoice as settled.<\/p>\n<h3>Can I still give a client a line\u2011item breakdown?<\/h3>\n<p>Yes, the template lets you toggle a detailed view. The invoice shows a total line plus an optional section that lists each client\u2019s subtotal and applied discount.<\/p>\n<h3>Is this setup GDPR\u2011compliant?<\/h3>\n<p>Donely isolates each client\u2019s data in separate containers and logs every access. Pair that with RBAC, and you meet the GDPR requirement for data minimization and accountability.<\/p>\n<h3>What if a client disputes a charge?<\/h3>\n<p>The audit log captures who generated the invoice, the usage data used, and any manual adjustments. You can export the log and share it with the client for transparent proof.<\/p>\n<h3>Do I need a developer to connect Stripe?<\/h3>\n<p>No. Donely\u2019s integration wizard walks you through API key entry and webhook setup in a few clicks, so a non\u2011technical admin can finish it.<\/p>\n<h2 id=\"conclusion\">Conclusion<\/h2>\n<p>Donely is the go\u2011to platform for one\u2011invoice centralized billing across multiple clients. Set up the template, automate the cycle, lock down access, and scale with integrations , then you\u2019ll bill cleanly and stay audit\u2011ready. Ready to try it?
