Custom software in Irapuato, from a team based in Irapuato.

Nightly Software is a software development studio based in Irapuato. We build custom software, meaning systems designed around how your company works, for local businesses: batch inventory, production control, orders, quotes, WhatsApp updates and websites. Since we’re in the same city, we can visit your business the same week, and you deal directly with both founders.

The problem

What holds many Irapuato businesses back

If any of these sound familiar, it’s worth a conversation. The consultation is free.

  1. 01

    Batches you can’t trace

    When a customer complains about a box, nobody knows which batch, day or supplier it came from.

  2. 02

    Stock that doesn’t add up

    The cold room, the warehouse and the spreadsheet all say something different.

  3. 03

    Orders scattered across WhatsApp

    Each salesperson writes them down their own way, and someone re-enters everything in the afternoon.

  4. 04

    Quotes that take days

    Putting one together depends on a single person digging for prices across several files.

  5. 05

    Customers can’t find you on Google

    People searching for what you sell in Irapuato don’t find you, or your website doesn’t say what you do or how to reach you.

  6. 06

    Reports built by hand

    To know what you sold or produced this week, someone pulls the numbers together on Saturday.

What’s included

What we build for Irapuato businesses

Irapuato is home to agribusiness (strawberries, vegetables, frozen produce and packing), manufacturing and automotive suppliers, plus thousands of stores and service companies. We start with the process that costs you the most today and add the rest in stages.

  • Inventory by batch and warehouse

    Raw materials, packaging and finished goods, with batch, date and location: warehouse, cold room or branch.

  • From supplier to customer, by batch

    Each batch records which supplier it came from, when it was processed and which customer it shipped to, with barcode labels.

  • Production and packing orders

    What gets processed, how much, with which materials and who’s responsible, with progress in plain sight.

  • Orders, quotes and collections

    Orders at each customer’s prices, quotes as PDFs and balances up to date, connected to your invoicing when your system allows it.

  • WhatsApp updates

    Confirmations, reminders and delivery dates go out automatically, without anyone typing them.

  • Websites and online stores

    So people find you when they search for your line of business in Irapuato, with fixed-price packages from $8,000 MXN.

Frequently asked questions

What business owners ask us before getting started.

Yes. Nightly Software is a software development studio based in Irapuato, Guanajuato, run by two founders. Jonathan Perez handles design, product and sales; Jair Chavez handles the technical side you don’t see: servers, data and security. We’re not the sales office of a company from another city, and we’re not a middleman who outsources the work: the people who visit your business are the people who build your system. That matters in practical ways. If something breaks, you message the same WhatsApp number as always, +52 462 221 2236, and one of us answers. And if we need to look at something in your warehouse or office, we’re a few minutes away, not a trip away.

Usually the same week you reach out. There’s no trip to arrange: we agree on a time and come to your warehouse, plant, office or store. On that first visit, we follow an order from the moment it arrives: where it’s entered, how product moves and at which step time or information gets lost. If you’d rather start without leaving your desk, the free consultation can also be a video call booked from our scheduling page. Then we send you a written proposal with the scope, the stages, the price of each stage and its dates. During the project, reviews can happen at your business or online, whichever suits you.

Yes. According to Irapuato’s city government, the municipality combines an agro-food economy with an automotive and auto-parts industrial base, and it ranks first in Guanajuato for agro-food exports, at US$702 million. According to the state government, in 2025 Irapuato accounted for 76.1% of the value of the state’s strawberry exports, including fresh, frozen and processed fruit, and 10 companies in the municipality export strawberries to the United States. In a business like that, what matters most is knowing which batch went into each shipment, how much product is left in each cold room and what each supplier delivered. A custom system records receiving, processing, packing and shipping, with the batch at every step, so you can answer a complaint with data instead of memory.

That works too. Irapuato isn’t just farmland: according to INEGI’s 2024 Economic Census, the municipality has 9.3% of Guanajuato’s businesses and 10.6% of the people who work in them. And according to the city’s 2024–2027 Government Program, using 2020 census data, almost 4 in 10 employed people in Irapuato work in services, 1 in 4 in industry and 1 in 5 in retail and wholesale trade. For stores with one or more locations, we have Ventrack, our own point-of-sale system: it keeps taking payments when the internet drops and deducts stock by location. For factories, see Polymer, the system we built for Sumiplas, which went from Excel files to seeing every production order in real time. And for services, Cleanly used to coordinate cleaning jobs in several Guanajuato cities by phone; today it quotes, assigns staff and collects payments online.

The price depends on the scope, not the city. A single module, such as batch inventory or an automated reminder, can start from about $5,000 MXN. A larger project, such as connected inventory and orders, from about $15,000 MXN. A complete system with several connected areas and reports, from about $25,000 MXN, paid in stages. Adjustments, support and consulting start at $400 MXN per hour. You get the exact price in writing after the free consultation. Unless the proposal says otherwise, each stage is paid before it starts, not the whole project at once.

We have three fixed-price packages with a one-time payment for the build: “Your online presence” at $8,000 MXN, with up to 3 sections, a contact form and a WhatsApp button; “Your site, active and visible” at $10,999 MXN, with up to 6 sections, a blog, SEO (the work that helps you show up on Google) and your Google Business profile set up, so your business appears on Google with its location, hours and phone number; and “Your online store” at $17,999 MXN, with up to 10 sections, online payments and product and inventory management. Hosting, domain, SSL, email, backups and maintenance are included for the first year after launch; before it ends, we tell you what renewing them costs. Delivery takes about one to two weeks depending on the package, counted from when we have all your content. Invoices are available on request.

Yes, and it’s often the smartest move. In the consultation, we pick the process that costs you the most today, such as cold-room inventory, quotes or the orders that come in on WhatsApp, and solve it first. We solve urgent issues within hours, and most projects are ready in about a week. If you later want to add production, collections or a customer portal, it’s added as a new stage, with its price and date in writing, without rebuilding what already works. We move your data over from Excel so nobody starts from scratch.

We fix any defect you report within 60 calendar days of each delivery at no cost. If we need to come to your business to check it, we do. After that period, adjustments and support start at $400 MXN per hour, or we agree on a support plan in writing. You can also end the project whenever you want, paying only for the work done, and your data is always yours to export.
