Snappy uses systemd so stopping and starting services needs to use systemctl. Eg:

$ systemctl list-units --no-pager | grep webdm  webdm_avahi_0.1.service
                                                         loaded active running
 Avahi daemon
  webdm_snappyd_0.1.service
           loaded active running   Snappy WebDM

$ systemctl status webdm_snappyd_0.1.service

$ sudo systemctl stop webdm_snappyd_0.1.service   # needs sudo

$ sudo systemctl start webdm_snappyd_0.1.service  # needs sudo


Service files are in /etc/systemd/system. Eg:
$ cat /etc/systemd/system/webdm_snappyd_0.1.service
[Unit]
Description=Snappy WebDM
After=apparmor.service click-system-hooks.service
Requires=apparmor.service click-system-hooks.service
X-Snappy=yes

[Service]
ExecStart=/apps/webdm/0.1/snappyd
WorkingDirectory=/apps/webdm/0.1
Environment="SNAPP_APP_PATH=/apps/webdm/0.1"
"SNAPP_APP_DATA_PATH=/var/lib/apps/webdm/0.1"
"SNAPP_APP_USER_DATA_PATH=%h/apps/webdm/0.1" "SNAP_APP_PATH=/apps/webdm/0.1"
"SNAP_APP_DATA_PATH=/var/lib/apps/webdm/0.1"
"SNAP_APP_USER_DATA_PATH=%h/apps/webdm/0.1" "SNAP_APP=webdm_snappyd_0.1"
AppArmorProfile=webdm_snappyd_0.1

[Install]
WantedBy=multi-user.target


Hope this helps!
