Building a digital office for a small team used to mean expensive licenses and an IT contractor. Not anymore. With WordPress as a foundation, a handful of plugins, and a few free SaaS tools, a five-person business can run its entire operation for almost nothing. This guide lays out the complete stack — what to use for each job, and roughly what it costs.
The Modern Small Business Stack
You don't need enterprise software to look and operate like a professional company. The pattern that works: WordPress + a few focused plugins + free tiers of good SaaS tools. Own the pieces that hold your data (your site, contracts, attendance); rent the commodity pieces (chat, email) on free tiers.
Your Website & Online Presence
Start with WordPress. It's free, runs anywhere, and becomes the hub for everything else — from your public site to internal tools. You'll need a domain, hosting, and an SSL certificate (most hosts include SSL free). Once WordPress is live, the rest of this stack plugs into it.
Document Signing & Contracts
Every business signs things: client contracts, NDAs, consent forms, employee onboarding paperwork. Instead of printing and scanning, collect signatures on your own site with MerchantKits Document Signatures. Create a signing page, share the link, and every signature is stored with a SHA-256 hash and audit trail. Free for 50 signatures a month. The full setup is in how to add electronic signatures to WordPress.

Employee Management & Attendance
Once you have a team, you need to know who's working and manage time off. MerchantKits Attendance Manager handles clock in/out, shift scheduling, and leave management from the same WordPress dashboard — free for small teams. The step-by-step is in how to set up employee attendance tracking in WordPress.

Communication
- Slack — the free tier handles messaging and channels for a small team comfortably.

File Storage & Collaboration

Getting Started Today
Don't try to adopt everything at once. A sensible priority order:
- Website — your foundation.
- Contracts — so you never start work unsigned.
- Attendance & leave — once you have a team.
- Communication — Slack or Google Chat.
Start with the free tools, prove the workflow, and upgrade only when a manual process is actively costing you time. That's how a small team runs like a much bigger one — without the bill.
WordPress plus two MerchantKits plugins covers your website, contracts, and HR for $0. Layer free SaaS on top and you have a complete digital office for the price of hosting.
