Frequently Asked Questions
Common questions about Contasimple
Once the plugin has been successfully configured, every order that changes its state to 'Completed' will be queued to be automatically sent to Contasimple. The process might be triggered by many different means, for example, when an order is paid via a payment gateway, like Redsys, or when you manually mark an order as completed in the back-office, once you have verified a payment via bank transfer. Most likely the order will be immediately sent to Contasimple when the order status changes. However, in case an invoice cannot be instantly sent, due to either a high number of incoming orders to process or for whatever other reason, the process will be resumed again each time an order reaches the shop, until the queue is empty and all orders are sent. You can check the sync status for all completed orders at any moment on the Invoices section that the plugin will add to your WooCommerce menu entry.
Yes. While the plugin will automatically handle all new orders of the shop, you can export all previous orders by navigating to the WooCommerce > Invoices section and clicking the Create from previous orders button. You will be presented with a page that lists all completed orders that have not yet been queued for sync, this of course includes orders prior installing the plugin. You can check some or all of them and then pick the Create action from the actions dropdown list that appears on top. Orders added this way will not be synced automatically right now, but they will be added to the sync queue. Hence you can let the plugin send them automatically when a new order is completed or, if you want to sync right now, you can always navigate back to the Invoices page and manually trigger the process by clicking the Sync now button. Notice that in this screen you can filter invoices by fiscal periods. This might interest you in case that you want to add to sync all the invoices for an ongoing tax collection period, but do not want to do further action with already declared invoices from previous fiscal periods.
In contrast to other eCommerce platforms, WooCommerce does not do sequential numbering from the get go, but uses WordPress internal post identification system. Sharing ID with blog post and many other types of content means no sequential numbering is possible by default. To solve this, Contasimple will keep the count of your synced orders and will assign the next sequential number any time an invoice is successfully synced, based on the mask assigned to the corresponding invoice series. Masks can be customized on the WooCommerce > Settings > Integrations page. There are three configurable masks for regular invoices, negative rectification invoices (for refunds) and simplified invoices (tickets) since many countries, like Spain, have fiscal laws that require to keep track of each type separately. By default, each one is set at different values, so that you will be working with three different series for each type of scenario. However, you could play with this and set the same value for both regular invoices and simplified invoices, or even for refunds as well, to make them fall into the same series in case that you prefer it and your country does not have any particular requirement on this. To know how to form the desired mask, please log into Contasimple website and go to Settings > Invoices, there you will find more information and examples.
This plugin uses WooCommerce built-in emailing system to deliver the invoice emails to your customers. If you go to WooCommerce > Settings > Emails you will see that you have a new type of email listed Order invoice. Like all WC email types, you can enable or disable it here and also change a few things, like the default subject or if you want it to be a plain text email or a fully fledged HTML template. Default templates provided for the Contasimple invoice emails include only a brief message and the generated invoice PDF as a file attachment because the default WC Completed Order email template already has an item summary and we feel that it would be redundant to include this info again. However, if you want -and know how to- you could customize the templates to suit your needs. Something to keep in mind is that, even if the invoice emails are set to enabled, only orders completed during the last 24 hours will be emailed automatically to your customers. We have set this restriction to avoid potential unwanted situations, like syncing all your previous year invoices just for historic purposes and then having all your customers emailed out of nowhere. You can always send an invoice manually as many times as you consider it necessary to a certain customer, by going to the plugin Invoices section and clicking the email action button for the desired invoice.
It really depends, but most likely no. As described in a previous section, Contasimple handles invoice numbering sequence in a very specific way, which is unaware of other installed plugins and which, conversely, does not expect other plugins to hook into it. Therefore, if you have other plugins installed, most likely you will end generating duplicated invoices for your orders and with totally different numbering series. If you finally decide to use the Contasimple plugin to generate legally compliant invoices for your orders, we strongly recommend to disable all other invoicing plugins that you might be trying or using during the past. If you feel that we are missing some very cool feature present in other plugins that ties particularly to tax legislation, feel free to contact us to suggest it and we will consider it.
Previous orders added manually to the sync queue use the configured mask under Contasimple settings, but will also add a random prefix to it. This is not configurable and it is done as a safety mechanism to avoid breaking fiscal laws. Most countries require invoice numbering series to be sequential but also to respect issuing order. Imagine that you install and configure the plugin and get a few incoming orders that get instantly synced to your Contasimple account, but then you decide to have a look at the existing orders for the whole current year and want to sync them as well. You would end with an incorrect issuing sequence. This is why Contasimple adds a random prefix each time a manual invoice creation is performed. This means you can end with a few different batches of invoicing series, which might seem not ideal. However, most countries fiscal laws allow to have different invoicing series if it can be justified, as long as the issuing order for each series is respected.
With some limitations, yes. Assuming you have still not synced any invoice to Contasimple or that you can delete in Contasimple Web the already uploaded ones so that you can start back from scratch, you can: (Optional) Disable your shop to avoid any orders to sync automatically during this process. WooCommerce does not allow this by default but there are plugins that allow you to. Set the desired numbering series format in WooCommerce > Settings > Integrations > Contasimple keeping in mind that 4 additional random numbers will be added first during the already existing orders sync process. Navigate to the Create from previous orders, mark as selected all the desired orders and click Create from the bulk actions drop-down control as described previously. Navigate back to Invoices and click the Sync now button. The page will reload with the sync results (might take some time). If all invoices are synced OK, you can proceed to next step. In case there were any errors present, they must be solved before continuing so that you do not miss any invoice (see the next FAQ section). Once all previous orders have been synced, write down (or just copy/paste) the 4 random digits appended to all invoices. Finally, you can go back to the plugin settings and modify your numbering series mask format to add these 4 digits before the already defined masks. This way, all new incoming orders will respect the same series when their status changes to Completed. Just keep in mind that anytime that you add previous existing orders to the queue, the plugin will create a new series to avoid the aforementioned numbering sequence mismatch.
Unfortunately, no. Or at least not without some additional work from your side. Contasimple only works with the currency configured in Contasimple Web for the desired fiscal region, since most countries mandate to declare taxes with its own currency. If you try to sync orders paid with a currency different than the one configured for your fiscal region, you will get an error. Accounting conciliation due to currency conversion is out of the scope of the plugin and you should configure your multi-currency plugin to work internally with only one currency, like WooCommerce does by default, and then try to sync to Contasimple. Note that, in its documentation, WooCommerce also recommends to work with only one currency internally (as it does by default) and handle multiple currencies for the customers by showing estimated conversions via the Currency Converter Widget.
At the time of release we only support single-site mode. However, we are already working on bringing multisite support and it should be available soon.
Most web hosting servers have a certain timeout set to abort long-lasting processes in order to save resources. If you have a lot of invoices pending to sync and depending on your server configuration, you might not be in time to sync all of them at once. The process will abort after a certain time passes (sometimes as short as 30 seconds) and you will get the infamous 504 error. If you have a dedicated VPS you might be able to configure Apache/Nginx timeout variable settings to greater values (ex: 5 minutes). You might be able to do so also on some premium shared web hosting services. In any case, you can always restart the syncing process from the Invoices section (or just wait for a new order to be completed) and the syncing queue will resume, so you will be able to sync all invoices eventually. However, we would recommend a quality hosting service where a sysadmin can fine-tune the settings to suit your goals.
