Installation
Installing GST Manager takes four steps: upload the plugin so its files are on the server, apply a one-time set of core hook points over SSH, activate the plugin, then enter your license and fill in your company details.
The order matters. The hook-point patcher ships inside the plugin, so the files have to be uploaded before you can run it — and you activate only once the hooks are in place. Before you start, make sure your server meets the requirements — especially the ionCube Loader and SSH access.
Step 1 — Upload the plugin files
In the AcelleMail admin, go to Admin → Plugins → Upload Plugin and upload the release archive (for example relyweb-gstmanager-vX.Y.Z.zip). AcelleMail extracts it to storage/app/plugins/relyweb/gstmanager/ and lists it as inactive. Don't activate it yet — apply the core hook points first.
Admin → Plugins → Upload Plugin
Step 2 — Apply the one-time core hook points
GST Manager needs four small extension points in your AcelleMail code — without them the plugin activates but its GST features (the GST invoice PDF, the GSTIN field, export numbering, and adding tax to order totals) stay silent. Apply them over SSH from your AcelleMail Laravel root (the directory containing artisan):
bash
./storage/app/plugins/relyweb/gstmanager/scripts/apply-core-patches.sh .The script is idempotent (safe to re-run) and pure PHP, so you don't need python or any extra tooling. This step is required and easy to get slightly wrong, so follow the full walkthrough — what it changes, how to verify it, and the important note to re-run it after every AcelleMail upgrade — in Apply the core hook points.
Step 3 — Activate the plugin
Back in Admin → Plugins, click Activate on GST Manager. Activation does the setup work for you: it runs the database migration, seeds sensible defaults (28 config keys and 38 Indian states), and mirrors the plugin's default GST rate into AcelleMail's own tax settings so new orders carry the rate from the moment they are created.
Step 4 — License and configure
Open the GST Manager entry in the AcelleMail sidebar. Because the license gates the whole GST admin surface, you enter your key first: go to Plugin Settings → License, paste your key and activate it. Until the license is Active, the dashboard, Setup and Reports stay locked.
With the license Active, move on to Setup and fill in your company GSTIN, home state, tax rate, invoice identity and bank details. The Configuration guide walks through every field.
