Hi, I reviewed the request to automate ERPNext so multiple Purchase Invoices from one supplier generate a single consolidated Sales Invoice, carrying all line items and details while keeping traceability. I’ll build a server-side custom app or short Python/Frappe script using ERP, Workflow Automation, and PHP, so fields like supplier name, original invoice numbers, payment terms, and each item’s full description populate natively and respect the permission model. I’ll ensure the function creates an exact item copy, generates draft Purchase Invoices in the background, avoids any core modifications, and delivers clean, repeatable workflow behavior. Let’s discuss here now.

Hi, I can build this as a clean, upgrade-safe ERPNext/Frappe customization that lets you select multiple Purchase Invoices from the same supplier and generate one consolidated Sales Invoice with every line item copied accurately. The solution will carry over the supplier name, original invoice numbers, full item descriptions and payment terms, while automatically creating/maintaining draft Purchase Invoices for traceability. I’ll implement it through a custom app or server-side Python script without modifying ERPNext core files, so it remains compatible with future updates and respects the existing permission model. Would you prefer the multi-invoice selection and consolidation action directly inside the ERPNext Purchase Invoice list/module for the most native workflow? Kindly send me a message to discuss more or directly award me. Thank you!

Hi, I can create a clean, repeatable workflow in ERPNext to automate the generation of consolidated Sales Invoices from multiple purchase invoices. To achieve this, I will develop a short Python/Frappe script that interacts with the ERPNext API. I will ensure that the script selects multiple purchase invoices from a single supplier and consolidates them into one Sales Invoice. Each line item will carry over the necessary details, including the supplier’s name, original invoice numbers, item descriptions, and payment terms. I will also implement a mechanism to leave behind draft Purchase Invoices for traceability in Accounts Payable. It is essential to respect the existing permission model and ensure that no core files are modified, allowing the solution to survive future updates. To get started, I will need access to your ERPNext instance and any specific configurations you have in place. Additionally, I will provide the code, a quick setup guide, and a short demo video or screenshots to confirm the solution runs end-to-end. Thanks!

@mak94pk

To automate your consolidation, I’ll first build a server‑side Frappe script that pulls selected Purchase Invoices, creates a Sales Invoice, copies all line items, and logs original invoice numbers. The script will run as a custom button, respecting the existing permission model and leaving draft Purchase Invoices behind. I can deliver a ready‑to‑install app, setup guide, and demo within 7 days. Do you have a test company with sample purchase invoices to validate the script?

I will build a migration-safe ERPNext/Frappe custom app for this invoice consolidation workflow, without modifying core files. I’ll add a native action to select multiple Purchase Invoices for one supplier, validate the supplier and prevent duplicate processing, then create one draft Sales Invoice containing an exact one-to-one copy of every source item, including quantities, rates, units, taxes, and full descriptions. The generated Sales Invoice will include clearly labelled supplier name, original invoice numbers, and agreed payment terms using custom fields or a structured section that fits the existing Sales Invoice layout. The server-side Python method will also create or preserve a draft Purchase Invoice for each original in the background, with links back to the consolidated invoice and source documents for Accounts Payable traceability. I’ll implement this through a whitelisted Frappe method, custom DocType fields, client-side selection logic, permission checks, and a transaction-safe rollback if any source invoice fails. Existing ERPNext roles and permissions will be respected, and the app will be installable through standard hooks/migrations so it survives future updates. I’ll provide the source code, setup guide, test-company validation, and a short recorded demo or screenshots covering the complete flow. Is the target ERPNext build v14, v15, or v16? Muhammad Saad

Greetings, I see that you're looking for a streamlined way to consolidate multiple purchase invoices into a single sales invoice in ERPNext. Your goal is to automate this process while keeping everything organized and traceable, which is essential for maintaining smooth operations. To tackle this, I would create a custom solution using Python and Frappe within ERPNext. This would allow users to select several invoices from a supplier and generate one consolidated sales invoice that retains all necessary details, like item descriptions and payment terms. I’ll ensure that draft purchase invoices remain in the system for reference, without altering any core files, so the solution stays intact during updates. I have experience with ERP systems and automation, which will help in delivering a solution that meets your needs efficiently. Best regards, Saba Ehsan

Hi, I’ve read your ERPNext invoice consolidation requirement carefully, and I can build a clean native workflow that consolidates selected Purchase Invoices into one Sales Invoice while preserving traceability, permissions, and upgrade safety. Using Python with ERPNext/Frappe, I’ll create a server-side custom app or script that copies every line item exactly, maps supplier name, invoice numbers, descriptions, and payment terms into clear sections, and generates the draft Purchase Invoices in the background without touching core files. I have strong Software Development experience delivering backend workflow automation and business logic customizations, and I’ll provide clean code, setup steps, plus screenshots or a short demo so you can verify the full end-to-end flow on your current build. I can start right away and deliver within 7 days. Would you like this launched as a custom button inside Sales Invoice, or from the Purchase Invoice list view? Best regards, KANIKA

@ShaikhAneesa

Hi there, I understand you need a native ERPNext workflow that lets users select multiple supplier Purchase Invoices and generate one consolidated Sales Invoice containing every source line item while preserving full traceability back to Accounts Payable. I’m confident I can implement this as an update-safe Frappe customization without modifying ERPNext core files. My approach is to first review your current ERPNext version, Purchase Invoice/Sales Invoice structure, permissions and required custom fields. Next, I’ll build the server-side Python/Frappe logic to validate the selected invoices belong to the same supplier, carry over every item, description and agreed payment terms, and record the supplier name and original invoice numbers clearly. I’ll also implement the background creation of draft Purchase Invoices while maintaining references to the source records. Finally, I’ll integrate the function into the existing Sales Invoice workflow, test the complete process against a test company, verify the one-to-one line-item mapping and permissions, and provide the code, migration-safe setup instructions and end-to-end screenshots/demo. Which ERPNext/Frappe version are you currently running, and are the supplier invoice numbers and payment terms stored in standard fields or existing custom fields? I’m ready to start immediately. Warm Regards, Aneesa.

Hello There! I’m Md. Toriqul Islam, an experienced Python/Frappe developer with 10+ years of experience building ERP workflows, custom server-side scripts, business logic, and API-driven integrations. I understand you need a native ERPNext workflow that selects multiple supplier invoices, consolidates their line items into one Sales Invoice, preserves supplier/invoice references, descriptions and payment terms, while keeping traceable draft Purchase Invoices. I am skilled in Python, Frappe Framework, ERPNext, server scripts, custom apps, DocTypes, permissions, database design, and update-safe customizations. I’m ready to start immediately and will avoid core-file modifications, provide migration-ready code, setup documentation, and demonstrate the complete workflow end-to-end. I have some questions: 1. Which exact ERPNext/Frappe version are you currently running? 2. Should the consolidated Sales Invoice use the customer selected manually or map to a predefined customer? Looking forward to hearing from you. Best regards, Md. Toriqul Islam

@sgrocean37

Hi, I understand the workflow: select multiple supplier Purchase Invoices → combine every line into one customer Sales Invoice → carry supplier/invoice/payment details across → keep draft Purchase Invoices for AP traceability. I’ve worked on custom business workflows and ERP-style automations where data needs to stay auditable and update-safe. I’d keep this outside ERPNext core files, with logging and validation so failed or partial runs can be reviewed safely. Two things I’d confirm: 1. Should all selected Purchase Invoices always belong to the same supplier and currency? 2. If the same item appears on multiple source invoices, should the Sales Invoice keep separate lines or merge identical items? Thanks, Sagar P.

@rbtech1984

Hello!! I understand you need an ERPNext workflow that consolidates multiple supplier Purchase Invoices into one Sales Invoice while keeping every item and document fully traceable. * Which ERPNext version are you currently using? * Should identical items remain as separate lines? * Do you already have the customer and supplier fields configured? The solution will use Python and Frappe without changing core files, with secure permissions, exact line-item copying, supplier and invoice details, payment terms, and automatic draft Purchase Invoices. Relevant ERPNext automation projects have been completed with clean, update-safe custom solutions focused on reliable accounting workflows. Let us chat and make this invoice process simple and fully automated. Best regards Farhin B

@seospider

Hello, Your workflow can stay fully upgrade-safe by using a small Frappe custom app/server-side action that consolidates selected Purchase Invoices into one Sales Invoice while preserving draft AP records and permissions. I’ve worked on ERP, inventory, financial software, workflow automation, Python backends, and database-driven business systems, so this type of traceable invoice flow is very familiar. I’d avoid core modifications and keep migration simple. Which ERPNext version are you using? Should the draft Purchase Invoices be newly generated copies, or should the selected originals remain as drafts? How are payment terms stored today? Best Regards Hasan

@Prutheus

Consolidating several purchase invoices from one supplier into a single Sales Invoice, while leaving traceable draft Purchase Invoices behind, is a clean Frappe server-side job. It has to feel native to the Sales Invoice module and respect the existing permission model. How I would do it: - A small custom app, not a patch of core, so it survives your next ERPNext upgrade - Server script that takes selected Purchase Invoices, maps every line item with description and payment terms, and writes one Sales Invoice with supplier name and source invoice numbers - Draft Purchase Invoices created for each original, linked back so Accounts Payable stays traceable - Permission checks via the normal Frappe framework, no bypass - Test run on a demo company proving line-by-line equality I digitalized a wholesaler end to end, including order and invoice tooling across 18 production services. One question: which ERPNext version are you on? Martin
