Every time I open VisionPoint to create a new purchase order, “ghost” line-items appear—records that were never added, don’t show on the printed PO, yet linger in the database and stop me from saving. The problem started the moment I tried entering a fresh purchase order and now happens on every single attempt. I need someone who knows their way around VisionPoint’s backend (tables, data integrity routines and any related SQL/Visual FoxPro utilities) to: • Locate the underlying cause of these ghost items. • Clean the current data so no phantom records remain. • Validate that new purchase orders save and print correctly without introducing more stray records. • Provide a brief summary of what was fixed so I can prevent a repeat. If ...
I need to retire my old Microsoft Access commission-tracking database and move everything to a cloud-based interface that staff can reach from any browser. You will start with the full Access file (forms, queries, VBA, and data) and rebuild the same business logic online. Two elements must make the jump intact: • Customizable commission calculations that let me change rates, tiers, and effective dates without touching code. • Built-in reporting and analytics so managers can slice results by salesperson, product line, and period, then export to Excel or PDF. Beyond those, I’m happy to discuss best practices—user authentication, audit trails, or dashboards—if they fit naturally into the new architecture. I have no fixed preference for the front-end stack; f...

I’ve uploaded a small bundle of C++ source files, their accompanying database dump, and the HTML / CSS front-end that sits on top of them. A few issues crept in that I can’t pin down: • the C++ code will not compile cleanly – basic syntax errors keep popping up • the database schema needs a quick rationalisation for speed and consistency • several layout glitches appear in the HTML / CSS, and the labour-cost figure returned to the page is wrong What I need from you is simple: return fully working copies of each file along with a brief note of what you changed and why, so I can follow the fixes later. Tested, readable code is a must; if you use tools such as clang-format, MySQL Workbench, or browser dev tools, great—just mention them so I know ho...

I have a data-analysis assignment focused solely on cleaning a dataset I refer to as “Point 131.” The current raw file shows a CPM value of 116 but contains inconsistencies, blanks, and probable entry errors that must be resolved so the final table reflects 100 % accuracy. What I need from you is a systematic, well-documented cleaning pass: remove duplicates, correct obvious typos, standardize formats, flag outliers, and leave me with a pristine file plus a brief change log that explains every edit. I am not under time pressure, so you can take the time required to reach the highest quality standard rather than rushing through. You may use whichever tools you are most comfortable with—Python (pandas), R (dplyr), Excel Power Query, or any reliable data-wrangling environm...

I’m running PerfexCRM and need two improvements that will streamline our daily workflow: 1. Separate invoice sequences • “Donation Receipt” must generate its own running number series. • “Regular Receipt” should follow a completely different sequence. I’m undecided on whether each series should reset annually or roll forward forever, so I’ll look to you for the best-practice recommendation and the logic to back it up. 2. Hebrew calendar support (similar to Kaluach) The CRM should display and work with Hebrew dates for: • Event scheduling inside the calendar and project modules • Fast Gregorian↔Hebrew date conversion on any date field • Automatic holiday reminders so our team can pl...
I need a clean, share-ready Notion workspace that lets our charity plan and run the upcoming music festival entirely around event scheduling. The heart of the build is an artist schedule presented in an easy-to-read weekly view so the team, performers, and volunteers can see who is on which stage at a glance. What I have in mind is a relational database driving a calendar view filtered to “Artists” entries, complete with time slots, stage/location fields, and quick links to each act’s tech rider and contact details. Drag-and-drop rescheduling, colour-coded stages, and simple search filters should make last-minute changes painless. If you can weave in reminder notifications for critical milestones or sound-check windows, that would be a bonus, but the core deliverable is ...

I’m ready to move our data into a brand-new Azure SQL Database instance and need a seasoned SQL developer to take the lead from design through deployment. The job starts with a clean slate—no legacy SQL Server to worry about—so I want a solid, future-proof schema that follows best practices for normalization, indexing, and naming. Your work will cover: • Designing the database structure and providing the DDL scripts to create it in Azure SQL Database • Configuring the instance for performance, security, and scalability (firewall rules, Transparent Data Encryption, role-based access, automated backups, etc.) • Writing any necessary stored procedures, views, or functions to support day-to-day operations • Supplying clear documentation and a qu...
I’m ready to centralise every part of my construction business in one purpose-built ERP. The system has to cover our day-to-day site work, back-office finance and everything in between, so stability and ease of use across job sites are non-negotiable.

Access & devices The application must run smoothly on desktop, mobile and any modern browser so supervisors can log u...
I need a robust, cloud-hosted database that can safely store and retrieve large volumes of transaction records for my application. At this stage I am still open to advice on whether a relational SQL solution or a NoSQL alternative will serve me better, so part of the job is to walk me through the trade-offs and recommend the architecture that best balances scalability, speed, and cost. Once the platform is agreed, I will look to you to design the schema (or data model), implement the database online, seed it with some sample data so I can run realistic tests, and deliver clear connection details for my dev team. Security best practices—encryption at rest and in transit, sensible indexing, parameterized queries or their equivalent—are essential. Deliverables • Technical...

I need a streamlined tracking and archiving system that lets my construction team capture three critical data streams—employee activity, project status, and equipment usage—and roll them into a single, at-a-glance dashboard. Think of it as our daily command center: supervisors should be able to log in, see real-time updates, and drill down to historical records without shuffling through spreadsheets or paper logs. Core expectations • A structured back-end (SQL, PostgreSQL, or another reliable database you recommend) where those three data categories live in clearly separated tables but can be cross-referenced quickly. • A web-based dashboard—desktop first, mobile responsive—showing live summaries, colour-coded alerts, and simple filters for date range...
