What it does
Singapore-native HR, Accounting, and e-Signatures in one app. Payroll with full CPF/SDL/IRAS compliance, double-entry accounting with GST 9% and InvoiceNow e-invoicing, plus DocuSign-style document signing — all behind one login. Flat pricing: S$29/mo for all three modules, not S$5/employee. A 30-employee company pays S$29, not S$214. Your headcount grows, your bill doesn't. 14-day free trial, no card required.
HR & payroll, accounting, GST returns, and InvoiceNow e-invoicing in one Singapore-native cloud platform. CPF, IRAS, and GST handled natively — purpose-built for Singapore SMEs.
Invoicing, journals, financial statements, bank reconciliation, GST F5 returns, CPF payroll, IR8A/IR21, leave, claims, and e-signing — with InvoiceNow e-invoicing via Peppol built in for the 2026 mandate. Stop stitching payroll, books, and signing across three separate tools. One login, one source of truth. Employees, CPF/SDL payroll, payslips, leave, claims, and year-end tax forms. Invoicing, GST F5, InvoiceNow e-invoicing via Peppol, banking, and reports. Signature requests, public signing links, certificates, and a full audit trail. Global platforms bolt Singapore compliance on as an add-on or integration. Critical Mass Cloud was built for it from the ground up — Peppol e-invoicing, CPF…from criticalmass.digital

VisiSign – $0.10 per envelope e-signatures with no monthly feeMay 2026 · visisign.app · ▲7Most e-signature platforms charge: per seat, per envelope, API access fees, enterprise contracts We built VisiSign with a different pricing model: $0.10 per envelope via API, no monthly minimum, no contracts, no seat pricing Or $49/month for the hosted team platform: unlimited users, unlimited sends, API included The reason this pricing works is simple: E-signatures are infrastructure now. Twilio doesn’t charge per employee. Stripe doesn’t charge per seat. Cloudflare doesn’t charge by company size. But most e-signature platforms are still priced like 2000s enterprise SaaS. It should…
Get e-signatures & pay per signed doc2024 · signwith.co · ▲27Woke up today with a 100-degree fever & found out Google is now our competitor. Last week, we started building signwith.co/ - a simple, pay-per-use e-signature tool for people who are struggling with complex e-sign tools. The plan was to build quietly, run a private beta, get 50 users in 15 days, and then do a launch. Easy peasy. But since Google dropped into the e-signature space - we needed to talk. So after 30 minutes of existential dread, a lot of “what are we even doing?” thoughts, and one strong dose of paracetamol we said, screw it. - let’s change gears. So now we're opening our…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

OpenSEO▲928Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
