    I run Odoo 19 on the free (community) build and would like it to talk seamlessly with the Intui platform. The goal is hands-off order management: as soon as an order appears in Intui it should land in Odoo, and if that order is changed or cancelled later, the same change must show up in Odoo in real time. Beyond the order itself I also need the integration to pull across the related customer record and keep product inventory levels accurate in both systems. Whenever a sync problem occurs I want an automatic email alert so I can react immediately; silent logging alone isn’t enough. I expect you to deliver an installable Odoo 19 module (Python, XML, possibly JavaScript for UI tweaks) plus clear setup instructions and a brief test plan that proves: • new Intui orders create corr...

    I need to set up a reliable routine that pulls our sales records from CRM and outputs them as standards-compliant XML files that match a simple schema I will supply. The assignment is strictly about getting data out of CRM. no importing or transformation inside the platform—so the focus is on clean extraction, correct field mapping, and well-structured XML. If you have questions about the schema or the target environment, let me know upfront so we can keep the turnaround tight.

    I’m spending far too much time re-typing purchase vouchers into Tally when everything is already organised in Excel. I need a small utility that reads those spreadsheets and posts each row as a purchase entry in my Tally company, with all taxes, supplier details and inventory lines carried over exactly as they appear in the sheet. You are free to choose the most efficient route—Tally XML import, ODBC, TDL, or a Python/.NET bridge—so long as the final result is a one-click (or near one-click) process that any non-technical staff member can run on a Windows machine. Deliverables • Executable tool or script with a simple UI or clear command-line instructions • Mapping configuration so I can point new spreadsheet layouts to the correct Tally fields without cod...

    • Description The objective is to create a prototype that sends our XML string via AS4 to a destination URL. You can start with <test>dummy</test> for now, but we will test with real xml. You will need to sign with the internal private key certificate and encrypt with the external public key certificate. The other side will decrypt with their private key certificate and verify our signature with our public key certificate. We will give you the certificates. You will then listen to our URL. They will send an async message 10-15 minutes later. We will give you access to our VPS, so the DNS will be routed to the VPS. You will need to verify their signature with their public key and decrypt the message with our private key. Success metrics are that the message is successfull...

    I need a straightforward Android application that lets registered grocery users browse a product pricelist and narrow it down by local brand name. When an item appears on-screen it should show only two fields—price and a short description—so the layout stays clean and readable. Core flow • A user signs up (or logs in) under the single available category: Area in which user is located. • Once inside, they see the full grocery pricelist pulled from a small dataset or back-end of your choice. • A filter control lets them pick the local brand they’re interested in, instantly updating the list in place. • An optional image upload screen is required so that I, as the admin, can attach a product photo or company logo for future use, even though image...

    I am running an existing Odoo installation (the system shows simply “Odoo” rather than a numbered release) and need a developer who can tailor it to fit my business. The priorities include adjusting screens and flows so day-to-day work is faster, adding or extending modules where current functionality comes up short, and making sure any changes remain upgrade-safe. You would start by reviewing my current database and the areas I find slow or cumbersome. From there we can agree on a small proof-of-concept change, then move to the broader tweaks and new features I have in mind. Clean, well-commented Python code, XML views, and clear deployment instructions are essential so I can maintain the custom work in the future. Please let me know your relevant Odoo experience, especially...

    I’m refreshing my website and need clear, easy-going copy that simply tells visitors who we are, what we do, and why they should stick around. The sole purpose is to provide information—no hard-selling tactics—so the wording should feel conversational yet still reflect our professionalism. Here’s what I’m after: • Complete website copy, ready to paste into each page (Home, About, Services, and Contact are the core sections I have in mind). • A consistent, casual tone of voice throughout, free of jargon and heavy marketing language. • Naturally placed keywords that help with basic on-page SEO without sounding forced. • Brief calls to action that guide readers to learn more or get in touch rather than “buy now.” I&rsquo...
