Sistema de Estoque Simples: how small businesses trade the spreadsheet for real control

The problem every small business knows

At some point, every small or mid-sized business that sells physical products hits the same wall: the inventory spreadsheet no longer matches reality. Someone forgot to log an outgoing sale, a formula broke without anyone noticing, two people edited the same sheet at the same time and one overwrote the other. The result is always the same kind of pain — buying more of a product that was already sitting there, or discovering an item is out of stock only when the customer is already waiting at the counter.

The problem is not a lack of discipline from the team. It is that a spreadsheet was never built to control real-time inventory with multiple people editing at once. And the next step, hiring a traditional ERP, usually trades one problem for another: months-long implementation, screens with too many options, long training, and a monthly fee that only makes sense for much larger operations.

What Sistema de Estoque Simples is

Sistema de Estoque Simples was built exactly for that middle ground: an online inventory management system made for businesses that need real control — not a giant bundle of features they will never use. Product registration, incoming and outgoing stock, customers, and suppliers in one clean interface, without the learning curve of a corporate ERP.

How it works

1. Create your account in under 2 minutes. No credit card required — you get 14 days free to try everything with no commitment.
2. Register your products with an image, SKU, barcode, and minimum stock level. Fast, no red tape.
3. Real-time control. Every incoming item, outgoing sale, or adjustment updates the stock balance immediately — no spreadsheet, no broken formula, no outdated version circulating by email.

What's included

• Incoming and outgoing stock with a draft → confirmed flow, with automatic stock updates and a full history of every movement.
• Automatic ABC curve, which classifies products into A, B, and C by sales volume — showing exactly where to focus attention and working capital.
• Reports in PDF, Excel, and CSV, ready to hand to your accountant or bring into a meeting, no need to build a spreadsheet from scratch.
• Daily low-stock email alerts, flagging products that are out of stock or below the configured minimum — before the customer asks and the answer is "we don't have it".
• Customer and supplier records, with purchase and sales history visible in one click.
• Two-factor authentication, with full access logs — the kind of security usually reserved for much larger companies.
• Quick stock adjustment directly from the list view, no need to open another form to fix a quantity.
• Per-product history, showing who changed what, when, and by how much — essential for resolving any discrepancy without relying on someone's memory.
• Duplicate recurring orders with one click, for anyone who buys or sells the same items from the same partners over and over.

Plans for every size of operation

Sistema de Estoque Simples does not force anyone to pay for a feature they will not use:

• Starter — R$ 49.90/month: up to 2 users and 500 products, with incoming/outgoing stock, adjustments, customers, suppliers, and PDF receipts.
• Pro — R$ 99.90/month (the most popular): up to 5 users and 5,000 products, with automatic ABC curve, daily low-stock alerts, and advanced reports.
• Business — R$ 199.90/month: unlimited users and products, full history, and dedicated support, for operations with more people using the system at the same time.

Every plan starts with 14 days free, no credit card required — enough time to test your business's real workflow before deciding anything.

Who it's for

For the small retailer still tracking inventory on a spreadsheet or a notebook. For the distributor who needs to know, without calling the warehouse, what is available right now. For anyone tired of paying a premium for an ERP that solves problems their business does not even have, when all they wanted was one simple thing: open the system and trust the number on the screen.

If that sounds like your operation, it is worth checking out Sistema de Estoque Simples and trying the 14 days free. Sometimes the difference between running on guesswork and running under control is not a six-figure ERP — it is the right system, the right size, working from day one.
